Yesterday I was in Dowagiac visiting friends and noticed some rather large mushrooms growing under their Black Oak in the neighbor's yard. I snapped a few pics. I think they might be Parasol mushrooms...but I could be wrong.
The stalk was slightly brown, and the cap had some small scales, cap mostly white except for a brownish nipple-like bump in the middle.

Found a few that looked somewhat like that a couple days ago. See my agaricus post in this forum. Unfortunately, mine was chlorophyllum molybdites. The green spored parasol(poisonous)
Did you get a spore print? Pick specimens?

I would be shocked if those weren't also chlorophyllum molybdites. They don't have the scales on the cap that are typical, but we've had some hard rains. I give five to one odds that these specimens had a green spore print.

Didn't get a spore print. I figured they were probably poisonous mushrooms. They do look like Chlorophyllum molydites, judging by the color and the small scales on the caps. The scales didn't show up well in the photographs but they are there.
Since they were in a neighbor's yard, I didn't pick any. I added a photo that shows some scales on the cap.
It is important to note that the Chlorophyllum molybdites often grows in fairy rings, and should not be confused with the edible Fairy Ring Marasmius, which is a lot smaller.
I was told my cousin got sick from eating fairy ring mushrooms...possibly these.
If you think about it, someone finds out that fairy ring mushrooms are edible, sees a large ring of these, and assumes that these are the edible ones, they are probably going to pick these large mushrooms instead of the small marasmius.
Here's a photo of one I didn't use in my original post because of the plantain stalk in the way.
